Diopter Post List 2017-05-03T05:54:04+00:00

Diopters.  We stopped calling glasses “prescriptions” a while back, since we don’t believe a reasonable educated individual needs a so-called professional to tell them which piece of clear, curved piece of plastic to buy.  (or conversely, keep you from making your own diopter choices)

If anything, we believe that most of the mainstream will give you more diopters than you need, causing progressive myopia and all sorts of long term risky side effects.  We feel strongly about education you on the subject of testing your own refraction, of making your own diopter choices.  Glasses are far less dangerous than lots of over-the-counter drugs!  Read this section for all things related to diopters, learn about the fascinating world of bending light (to your will).    

Newbies! Stop Reducing Too Much

There are a few recurring themes with kittehs getting started with getting that lens monkey off their back (or ... nose). The most recurring one is, newbies reducing too many diopters all at once. I get five billion e-mails and messages, all asking this same question.  Hey, Jake.  Is it ok if I reduce my diopters by ... half?  Hey Jake, I'm -5. How about if I go to -3.  Would that be ok, Jake?  Hmmm?  What do you think [...]

Long Term Uncorrected Low Myopia Blur Adaptation

Pro topic. You may have low myopia (below 2 diopters) and simply never started wearing glasses.  While in principle this is a smart move towards protecting your distance vision from lens-induced myopia, it doesn't alone address your existing myopia degree. It also creates an issue of habituated blur, something you'll have to address before being able to make meaningful progress in eliminating the low degree myopia. A question on this topic from the BackTo20/20 support forum: Smart self assessment. Here's [...]

Q&A: Can I Reduce More Diopters For More Gains?

Generally speaking, you can reduce by 0.50 diopters - but quite likely you shouldn’t. In some cases (high myopia) it can make sense to do so – see here a more detailed breakdown. But then also reducing diopters more just means that you’re reducing your distance to blur.  Seen clearly less far doesn’t really improve your vision at all – so does it make sense to make your diopter bubble smaller by half diopter? Stimulus is key to improvement.  Blur [...]

Pro Topic: One Eye Improves Quickly, The Other Does Not (Why?)

You're working on your eyesight.  Things are going well. Except, not really.  You got one eye improving like a champ, and the other is lagging.  It's making you a little nutty, and you wish you knew what is going on.  If this is the case for you, read on! This is a scenario that comes up every so often, that warrants a bit of an entry in the freeloader blog guides section. Because of course and fortunately you have your [...]

Matthew: Dropped Diopters Too Fast, Hit Plateau

Just can't wait to drop those diopters?  Are you smarter than the last of the living eye gurus?  Did you say hey whatever, I can hazz what I wantzz!  Drop the diopterzzz now! Good for you.  Learning things the hard way. But then again, that's common.  Even a darling eye guru started out by reducing a -5 diopter needed correction to -3 diopters and then immediately setting off (with just those glasses) on a trip to Laos.  You're in good [...]
